The characteristic property of hallucinogens, to suspend the boundaries between
the experiencing self and the outer world in an ecstatic, emotional experience,
makes it posible with their help, and after suitable internal and external
perparation...to evoke a mystical experience according to plan, so to speak...
I see the true importance of LSD in the possibility of providing materail aid
to meditation aimed at the mystical experience of a deeper, comprehensive
reality. Such a use accords entirely with the essence and working character
of LSD as a sacred drug.
